The unexpected origins of 12 classic sci-fi movies

What made Avatar—the biggest movie of all time—so damn popular? Sure, the amazing visuals and innovative 3-D created a one-of-a-kind experience, but it seems likely that the storyline captured audiences' imaginations as well. Now, we're not about to say thatAvatar's plot is original—in fact, far from it.
Avatar is derived from a story that has been told plenty of times before—the modern man confronting a native civilization—but that may be exactly why it captivated moviegoers. The story is classic, almost archetypal, and it has been told again and again throughout the years, always finding a new audience.
So that got us thinking: What other renowned sci-fi movies are based on source material that is so classic, so iconic, that it can be retold in new ways, generation after generation? We found quite a few, actually. Some are based on legends, some on myths, one or two on philosophical concepts. But they have all held up and formed the basis for some pretty sensational sci-fi masterpieces.
